I see the sights lift and return on each shot. It happens very fast obviously and when you go that fast what you need to see to break the shot changes from a very precise shot at 25 yards. Its like the difference between the focus needed to make a ball hanging in the pocket and a length of the table straight in down the rail.
I know and have taken classes with some of the best shooters in the world both competition and guys who shoot people for a living. To a man they tell you basically the same thing: Use your sights if at all possible. If an instructor advocates point shooting past anything over three yards it tells me all I need to know regardless of what he says his background is.
In speed shooting there is a saying: You can only shoot as fast as you can see. Meaning you need to know what you have to see to get the result the you are looking for. If its two shots in .30 seconds at 10 yards it looks much different than 2 shots in a second at 50 yards. Both situations require seeing what you need to see though not just relying on instinct.
As for pool the instructors here are much more knowledgeable than I. If a not aiming aiming system improves peoples games then its great.
Re: The elite units and point shooting. I cant think of anyone more high speed than CAG. Here is what one of guys who taught the current generation of Delta shooters has to say on point shooting:
